Hongfa Europe GMBH Signal Relay Surface Mount DPDT 24V DC Coil 2A Gold-Plated Contacts HFD3/24

The Hongfa Europe GMBH HFD3/24 is a high-quality signal relay designed for precise switching tasks in electronic and industrial applications. This surface mount relay features a DPDT (Double Pole Double Throw) configuration, allowing for two independent circuits to be controlled simultaneously. With a coil voltage of 24V DC, it delivers performance suitable for both low- and high-frequency signal circuits, control systems, and instrumentation panels.

The relay incorporates gold-plated contacts to minimize signal attenuation, improve conductivity, and ensure long-term operational reliability. Its compact outline of 15.0 x 7.5 x 9.0 mm makes it ideal for tightly packed PCB assemblies where saving space is critical. Surface mount PCB terminal connections enable convenient soldering and strong mechanical stability on the board.

This model is rated for a maximum switching current of 2A, handling both 277V AC and 220V DC circuits. With a coil resistance of 4100Ω and power consumption at only 140mW, the HFD3/24 is designed for energy-efficient operations in continuous and intermittent switching environments. The bifurcated contacts and advanced construction support reliable contact performance, even in demanding use cases.

Engineered for robust performance, the relay operates reliably across a wide temperature range from -40°C to 85°C. The contact resistance is rated at 100mΩ, maintaining signal integrity even under frequent operation. SMT and DIP types are available, and the design provides environmental compliance including RoHS certification as stated on the product page.

Typical applications include industrial automation, data transmission, test and measurement equipment, communication modules, signal switching circuits, and instrumentation panels where dependable, compact relays are required. Industries that benefit from this relay include electronics manufacturing, telecom, process control, and PCB design for control and instrumentation environments.

Outline dimensions are 15.0 x 7.5 x 9.0 mm, allowing for straightforward integration on dense circuit boards. Terminal type is PCB mount for rapid assembly. This relay’s gold-plated contacts and bifurcated contact design further ensure excellent performance where low-level or sensitive signals are switched.

For engineers and project managers searching for a reliable surface mount DPDT signal relay with a 24V DC coil and robust contact performance, the Hongfa Europe GMBH HFD3/24 provides a proven and efficient solution.
